IMPROVEMENT IN BAKERS OVENS.

Specification forming part of Letters Patent N o. 187,209, datedFebruary 6, 1877,- application led November 9, 1876.

To all whom 'it may concern:

Be it known that I, ALEXANDER WILSON, of Galesburg, in the county ofKnox and State ot' Illinois, have invented certain new and usefulImprovements in Bakers Ovens; and I do hereby declare that the followingis a t'ull, clear, and exact description thereof, which will enableothers skilled in the art to Which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersof reference marked thereon, which form a part of this specication.

The nature of my invention relates to improvements in bakers7 ovens; andthe invention consists in the use of a sliding cover, which is operatedfrom the outside ofthe oven, and so as to cover the openings foradmitting light to the interior of the oven, when they would be liableto be smoked or steamed, and to uncover said openings, when desired, forthe admission of light, as hereinafter more fully described.

The accompanying drawing is a perspective view of an oven, partly brokenaway to show my invention, which it embodies.

Referring to the parts by letters, letter A represents the walls, B thecrown, O the bottom, and D the door, of a bakers oven, which may be ot'any ordinary construction. E is an opening in one side, or at any othersuitable plaee'in the oven, and is provided with double lights of glassor mica, e c', in the usual manner. F is a cover for the side of theopening E, next the interior of the oven, and is seated in Ways ff, inwhich it may be slid back and forth, a stop, g, limiting its motion whenit is slid forward to cover the opening E, and also limiting its motionwhen it is drawn back to uncover the same. G is a rod or handle, at-

tached at one end to the slide F, and its other end extending outwardthrough the shell or casing of the oven, to within convenient reach ofan operator.

The advantagesof openings for the admission of light to ovens arerendered useless by reason of the smoke ofthe tire in heating, and thesteam in baking, obscuring the transparencies placed in the opening.These difficulties are removed by the use of the slide F, hereindescribed, which may be slid in to cover the opening E and pr'otect thetransparency e while the oven is being heated, and while the bread isgiving off much steam, and may be slid back to uncover said opening andadmit light'when placing the bread Within or removing it from the oven,and for other purposes.

I am aware that slides have been used on the inside walls of bakers7ovens, operated from the interior through the open door. I do not claimsuch as my invention.

What I claim as new, and desire to secure by Letters Patent, is

rIhe protecting-slide F, having stop g and handle Gr, the latterextending to the outside of the oven, operatingin combination with xedframe, with lights or transparent media u c c', and the walls A of abakers oven, substantially as and for the purpose specified.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

ALEXANDER WILSON. Witnesses:
